	* doc/invoke.texi (-fipa-struct-reorg): Do not mention
	-fipa-type-escape.
	* ipa-type-escape.c (gate_type_escape_vars): Run when

	* common.opt (fipa-type-escape): Remove.

	* gcc.dg/pr43317.c: Do not pass -fipa-type-escape.
	* gcc.dg/pr43084.c: Likewise.
	* gcc.dg/pr42250.c: Pass -fipa-struct-reorg instead of
	-fipa-type-escape.
	* gcc.dg/struct/wo_prof_escape_arg_to_local.c: Do not pass

layout in order to better utilize spatial locality. This transformation is
affective for programs containing arrays of structures. Available in two
compilation modes: profile-based (enabled with @option{-fprofile-generate})
or static (which uses built-in heuristics). Require @option{-fipa-type-escape}
to provide the safety of this transformation. It works only in whole program
or static (which uses built-in heuristics). It works only in whole program
mode, so it requires @option{-fwhole-program} and @option{-combine} to be
enabled. Structures considered @samp{cold} by this transformation are not
affected (see @option{--param struct-reorg-cold-struct-ratio=@var{value}}).
